Benefits of technology

[0025] (3) A three-dimensional display method includes the steps of generating a number of light rays proceeding in different vertical and horizontal directions by corresponding each individual lens to a two-dimensional light-source array as the individual lens of a two-dimensional lens array to be one pixel of

Problems solved by technology

However, when the moving photo-realistic image display is assumed, in a method in that a lenticular screen is bonded on the two-dimensional image display, the number of images capable of being displayed is limited by the resolving score in the horizontal direction displayed on the two-dimensional image display.
Therefore, the smooth movement parallax cannot be expressed so as to produce image skips, while there has been a problem of fatigue due to the contradiction between the focal point

Abstract

A three-dimensional display method and a device therefor are provided in which a number of images can be displayed in the horizontal directions while image skips can be eliminated by providing overlaps of display angular ranges between adjacent images having horizontal display directions.
A number of images are displayed in horizontal and vertical directions so that the display directions do not agree with each other, and by expanding vertical display angular ranges of entire images with a vertical-direction diffusion plate (17), a vertical display angular range common to the entire images is generated. In this common vertical display angular range, the entire images have different horizontal display directions. Thereby, a number of images can be displayed because image generating sources can be arranged also in the vertical direction in addition to the horizontal directions.

Description

TECHNICAL FIELD [0001] The present invention relates to a three-dimensional display method and a device therefor, and in particular relates to a three-dimensional display method and a device therefor in that a plurality of images different in display directions are generated in horizontal and vertical directions, so that a number of images different in horizontal display directions are generated by expanding a display angular range of each image only in the vertical direction with a vertical-direction (one direction) diffusion plate. BACKGROUND ART [0002] Human physiological factors of stereoscopic vision include binocular parallax, accommodation, congestion, and movement parallax. By satisfying these entire factors, a natural three-dimensional display is enabled. [0003] As is understood from that a human has a pair of eyes, among the physiological factors of stereoscopic vision, the most influencing factor on stereoscopic perseption is the binocular parallax in which stereoscopic i...
